Exploratorium Free Days

Exploratorium has no regular free day right now — here's what exists instead. The Exploratorium has no regular free day — its access program is 'Exploratorium for All': $5 tickets (up to 4) on site for anyone with an EBT/SNAP/CalFresh, Medi-Cal, WIC card, or Lifeline Pass. Its occasional pay-what-you-wish Community Days (traditionally Mother's Day) are one-off events, not a standing schedule. Date-specific tickets; access-program tickets sold on site only, not online Verified on Exploratorium's own page, last checked 2026-09-14.

Know before you go

• Who qualifies: Everyone (paid); $5 access tickets with EBT/SNAP/Medi-Cal/WIC/Lifeline.
• Reservations: Date-specific tickets; access-program tickets sold on site only, not online.
• What's covered: General admission.
• Worth knowing: Bay Area library cardholders can skip paying entirely — the Exploratorium is on the Discover & Go program, which lends free passes to it and dozens of other attractions through your local library.

Other ways in, no calendar required

• Museums for All is worth knowing for any museum trip: a SNAP EBT card plus photo ID gets up to four people in for free to $5 at 1,700+ participating institutions nationwide — during all normal hours, not just special days. Check whether Exploratorium participates on the official list.
• Science-center members from 90+ miles away may get in on the ASTC Travel Passport — the 90-mile rule is the catch, and our reciprocity lookup computes it for your ZIP.
